"© Licensed to London News Pictures. 07/03/2021. LONDON, UK.  A customer shops in the new 2,500 sq ft Amazon Fresh store in Ealing, west London on its first weekend of opening. It is the first ""just walk out"" grocery store in the UK and the first outside the USA.  As a ""contactless"" shop, it is available to anyone signed up to Amazon and with the app on their smartphone.  In-store cameras and artificial intelligence monitor customers picking up items who simply walk out and billing takes place later automatically.  Photo credit: Stephen Chung/LNP"
